//! A Rust port of [google-research/nasbench][NASBench]. //! //! [NASBench]: https://github.com/google-research/nasbench //! //! # Motivations //! //! Of course, the primary purpose of this crate is to make [NASBench] dataset available in Rust. //! Besides, another aim is to reduce dataset loading time. //! By using a compact binary data format, this crate can reduce the loading time drastically. //! For example, on my laptop, [google-research/nasbench][NASBench] requires about 200 seconds //! for loading the full dataset. By contrast, this crate only needs a few seconds to complete the loading. //! //! # Examples //! //! First of all, you have to convert a NASBench dataset to this crate's format as follows: //! ```console //! $ wget https://storage.googleapis.com/nasbench/nasbench_full.tfrecord //! $ nasbench nasbench_full.tfrecord nasbench_full.bin //! $ ls -lh //! -rw-rw-rw- 1 foo foo 328M May 12 16:47 nasbench_full.bin //! -rw-rw-rw- 1 foo foo 2.0G May 12 16:45 nasbench_full.tfrecord //! ``` //! //! Then, you can query the evaluation metrics associated with a model (`ops` and `adjacency`): //! ```console //! $ nasbench query nasbench_full.bin \ //! --adjacency 0100110001000000010010000010000001000000010000000 \ //! --ops input conv3x3-bn-relu maxpool3x3 conv3x3-bn-relu \ //! conv3x3-bn-relu conv1x1-bn-relu output //! EvaluationMetrics { //! training_time: 1769.1279296875, //! training_accuracy: 1.0, //! validation_accuracy: 0.9241786599159241, //! test_accuracy: 0.9211738705635071 //! } //! ``` //! //! Rust code corresponded to the above command: //! ```no_run //! use nasbench::{AdjacencyMatrix, ModelSpec, NasBench, Op}; //! # use trackable::result::TopLevelResult; //! //! # fn main() -> TopLevelResult { //! // Loads the dataset. //! let nasbench = NasBench::new("nasbench_full.bin")?; //! //! // Queries a model. //! let ops = vec![Op::Input, Op::Conv3x3, Op::MaxPool3x3, Op::Conv3x3, //! Op::Conv3x3, Op::Conv1x1, Op::Output]; //! let adjacency = "0100110001000000010010000010000001000000010000000".parse()?; //! let model_spec = ModelSpec::new(ops, adjacency)?; //! println!("{:?}", nasbench.models().get(&model_spec)); //! # Ok(()) //! # } //! ``` //! //! # Limitations //! //! [google-research/nasbench][NASBench] provides `NASBench.evaluate()` method to train and evaluate //! models from scratch, but this crate does not. //! //! # References //! //! - [NAS-Bench-101: Towards Reproducible Neural Architecture Search](https://arxiv.org/abs/1902.09635) #![warn(missing_docs)] #[macro_use] extern crate trackable; pub use self::dataset::NasBench; pub use self::model::{AdjacencyMatrix, EpochStats, EvaluationMetrics, ModelSpec, ModelStats, Op}; mod dataset; mod model; mod protobuf; mod tfrecord; /// This crate specific `Result` type. pub type Result<T> = std::result::Result<T, trackable::error::Failure>;
